Resetting the password in a laptop on the hard drive. Removing ATA password from HDD. List of known Master passwords
Hi all! I accidentally found a way to reset the BIOS password on a laptop without disassembling it. It's very convenient!
How to remove the BIOS password on a laptop?
All BIOS settings information is stored in a chip on the motherboard, and the battery on the board serves to store the information of this chip when the laptop is turned off or the battery is dead. And to reset this information, you need to disassemble it and remove the battery or unsolder it where it is soldered. Isn't it really inconvenient?
BIOS password generator
Therefore, I propose another method, without disassembly. I found a special program and translated it into Russian for you to make it easier to use. and we see the field in which you need to enter your code.
You can recover the password from laptops: Acer, Compaq, Dell, Fujitsu-Siemens, HP, Compaq, Insyde H20, Phoenix, Sony Vaio, Samsung. I'm not sure it will work on Asus, but try it.
Procedure
- We turn on the laptop and try to enter the BIOS, usually the F2 key.
A message appears, enter your password.
Enter any character set and press enter. The Invalid Password sign will appear.
We dial random numbers 2 more times and the BIOS will prompt you to enter a password to unlock or continue booting the system.
We choose to enter the unlock password (Enter Unlock Password).
A password will appear that you need to enter in.
In the service, enter this code and click get password.
Depending on your laptop brand, enter the received code in the field provided.
And press Enter. And we get into the BIOS.
Now go to the Security tab and remove the password. Press enter next to the set supervisor Password field and enter the password that we generated in the service, and in the second and third fields we do not write anything, just press enter.
And now we do the same thing in the Set HDD Password field, remove the password for loading the hard drive.
That's it, the password on the laptop has been removed from the BIOS.
Good afternoon, dear blog readers! Today we’ll talk about something less common, but important. I have never encountered such a problem as setting a password on the hard drive or BIOS. Probably many people don’t quite understand, and perhaps they don’t understand at all what I mean. Now I will explain in more detail.
BIOS password
BIOS is software located in a read-only memory device (ROM) that performs self-testing of devices and searches for the boot loader. Naturally, the functionality of the BIOS is much broader than described above, but we won’t dig deep, but will look directly at the topic of our article. The BIOS password is set to avoid manipulation by third parties.
How to remove the BIOS password
The set bios password does not make it possible to get into it, and in this case there are three options for solving this situation: resetting the BIOS settings by removing the CMOS battery on the motherboard, moving the CMOS jumper on the motherboard in the opposite direction (not provided in laptops), or simply close the jumper contacts.
And the last way to remove the BIOS password is using the online service BIOS Password Removal for Laptops. If you know the password and you just don’t feel comfortable entering it all the time, you can disable it by going into the settings.
HDD password
Here the purpose and function of the password is slightly different. If in the first case you simply cannot get into the BIOS, then with a password set on the HDD you will not be able to boot the operating system. And this is the inability to use a computer or laptop for its intended purpose.
How to remove password from HDD
If we looked at three options to solve problems with the BIOS, then in order to remove the password from the hdd I have only one for you, the same bourgeois online service. I didn’t describe above how to use this site. To unlock a password you don't remember, you need to enter it incorrectly three times (for example, 1234 or whatever you want). After the attempts have been made, a code will appear in the window, enter it on the website http://bios-pw.org/ and in response you will receive a code to reset the password from the hard drive.
How to put a password on your hard drive or BIOS
These passwords are set to protect data and from various manipulations. Every BIOS has this feature. Today's computers and laptops have a Security tab where you can set passwords. More details about this in the pictures.
Setting passwords on BIOS and hard drive Set Supervisor Password– set the Administrator password
Set User Password– set the User password
HDD Password– hard drive password
Password on boot Used to enable or disable the boot password.
Well that's it, my little article has come to an end. See you soon!

The hard drive is locked, although it’s only 8GB, but still that’s money too (:
When you turn on the computer and detect devices, having stumbled upon the definition of the hard drive, the computer displays a message
HDD Locked. Please enter the password
After researching the problem, I found a lot of interesting information regarding locked screws. After reading everything below, I did what is even below (:
There are paid solutions (expensive and 2 options with saving information (more expensive) and without it - cheaper).
Master passwords for HDD. Master ATA password.
Contrary to popular misconception, it is impossible to “lock” or “lock” a drive using the Master password. The master password can only be changed. The Master password can unlock the drive if the USER password is forgotten, but this is only possible if the security level was set to “High”. If the protection level is “Maximum”, then you can unlock the drive only by knowing the User password. If the protection level is “Maximum”, the User password is unknown, but the Master password is known, then it is possible to unlock the drive and destroy all data using the Security Erase Unit ATA command. This is implemented in MHDD (FASTERASE command), however this procedure in MHDD only works with User passwords.
Thus, a drive locked with the “High” security level can be unlocked using either the Master or User password. If the protection level is “Maximum”, then unlock
The drive can only be stored using a User password, or using a Master password, but with the destruction of all data.
Manufacturers set factory Master passwords, and if they are not changed in advance, they can be used to unlock a password-protected drive whose security level is “High”.
You can set the User password by issuing the PWD command to the MHDD. In this case, the protection level is set to “High”. The option to set a different level in MHDD is not available for security reasons. Also, the entered password is displayed in the mhdd.log file. After setting the password, the drive must be turned off.
Unlocking a drive that is password-protected with the “High” protection level is possible using a User or Master password. If the password is unknown, then, in general, it is impossible to unlock the drive, although there are two ways:
1. If the password is not encrypted by the drive itself, you can try to read it from the surface using technological commands;
2. Unlocking is possible using specially developed methods.
If the password is known, then the procedure for unlocking the drive in MHDD is as follows:
1. issue the UNLOCK command, select User password, and enter the password. This temporarily unlocks the drive (until you turn off the power).
2. issue the DISPWD command, select User password, and enter the password again. This completely removes the blockage.
According to the ATA/ATAPI standard, you cannot suppress the DISPWD command without first unlocking the drive with the UNLOCK command.
If the password is unknown and the protection level is “Maximum”, then you cannot do without special tools. If the password is unknown, and the protection level is “High”, and the Master password has not been changed, then it is possible to unlock the drive if you know the factory Master password.
List of known Master passwords:
Fujitsu hard drives: thirty-two spaces. In MHDD, you must enter 32 spaces when prompted for a password.
Seagate hard drives: the word “Seagate” without quotes, capitalized, padded with 25 spaces to 32 characters. In MHDD, when prompted for a password, you must enter the word Seagate followed by 25 spaces. Also, advice from one of the site visitors: if the password does not work, try entering the word SeaGate and 25 dots.
Winchesters Maxtor: the phrase “Maxtor INIT SECURITY TEST STEP” - case is important! There is one space at the end of the phrase. The password length is 31 characters.
Samsung hard drives: 32 "t" characters. In MHDD, when prompted for a password, you must enter 32 characters t.
Western Digital hard drives: the phrase “WDCWDCWDCWDCWDCWDCWDCWDCWDCWDCWD”, without quotes.
IBM hard drives:
DTTA series: "CED79IJUFNATIT", padded with spaces up to 32 characters. In MHDD, when prompted for a password, enter the given phrase, followed by 18 spaces.
DJNA series: "VON89IJUFSUNAJ", padded with spaces up to 32 characters. In MHDD, when prompted for a password, enter the given phrase, followed by 18 spaces.
DPTA series: "VON89IJUFSUNAJ", padded with spaces up to 32 characters. In MHDD, when prompted for a password, enter the given phrase, followed by 18 spaces.
DTLA series: "RAM00IJUFOTSELET", padded with spaces up to 32 characters. In MHDD, when prompted for a password, enter the given phrase, followed by 16 spaces. http://www.ihdd.ru/mhdd
Hitachi hard drives, DK23AA, DK23BA, DK23CA series: thirty-two spaces. In MHDD, you must enter 32 spaces when prompted for a password.
Toshiba hard drives, all episodes: thirty-two spaces. In MHDD, you must enter 32 spaces when prompted for a password.
Below are the User passwords set in certain situations by various popular programs:
MHDD versions 3.x, occurs when an internal error occurs: 32 letters “A” or 32 letters “B” (capital Latin).
HDDL, occurs when a quick erase attempt fails: “fuck.”
HRT: 32 characters with code 0. In order to enter such a password in MHDD, just press ENTER when prompted for a password.
HDD ERASE 4.0: when cleaning the disk, sets the password “idrive” - you can also use it to remove it!
That's just a program HDD ERASE 4.0 I had a locked screw, all because I didn’t wait for the “erase” to finish and rebooted the machine...
In fact, a detailed description of the operation of the security system is well described in the ATA-5 standard and higher. Also, a more convenient presentation, in my opinion, is available in the Product Manual on any IBM disk.
I will try to explain the essence in a nutshell.
Master password- a unique code that is stored in the service area of the drive, sometimes in encrypted form. On some hard drives it is present after leaving the assembly line and does not affect access to the hard drive. The master password is intended to delete the set user password (for example, if it has been forgotten).
Some manufacturers have their own Master password for a specific family of drives (model range). For other manufacturers, on the contrary, the Master password can cover quite a few models and lines. Any information about Master Passwords is not subject to public distribution and is the property of the manufacturer.
User password- this is a code of up to 32 characters in length, entered by the user using special utilities or using the corresponding function of the computer’s BIOS (present, mainly, only in NoteBook). The password is also stored in the service area of the drive and is also sometimes encrypted.
---
The security level can be High or Maximum.
1. At the High level, it is possible to unlock the drive using the Master Password, in this case all user data is saved.
2. At the High level, it is possible to unlock the drive using a User password, in this case all user data is also saved.
3. At the Maximum level, it is possible to unlock the drive using the Master Password, but in this case the user data is completely destroyed without the possibility of recovery.
4. At the Maximum level, it is possible to unlock the drive using a User password, while the user data is completely saved.
Accordingly, if the drive’s security mode is activated and neither the Master nor the User passwords are known, the drive cannot be unlocked. A locked drive must be detected correctly in the BIOS, however, it will generate an error for any read or write operation. And guessing a password using homemade brute force utilities is excluded - after five incorrect attempts, the drive goes into the Freeze state and can only be exited by turning the power off and on again. (http://www.hddr.ru/faq.htm)
A small caveat: If you set a user password in MHDD ver.4.0 (appears on Maxtor screws, possibly on others) for "FAST ERASE", then after this operation you should REMOVE the password WITHOUT REBOOTING, because It is possible that after a reboot the password cannot be removed using MHDD itself.
So, we have set the password.
MHDD -> read the documentation and remove using the unlock and dispwd commands. The data will be saved. (the password is removed by the _same_ version of the program that was installed)
Another option: After loading mhdd, turn off the power and try to remove the password, i.e.:
1. Download mhdd.
2. Remove the power supply from the screw.
3. Insert it back.
4. Type unlock and enter the password you set.
You can also try the ATAPWD program (http://rockbox.haxx.se/atapwd.zip):
1. ATAPWD: UNLOCK WITH USER/MASTER PASSWORD. The data will be saved.
2. ATAPWD: First we do ERASE PREPARE (Preparation for removing the user password by completely erasing the disk), then - ERASE UNIT. The data, of course, is destroyed.
Blank password.
Dmitry_Postrigan: A blank password in MHDD can be removed by entering the character with code 255 as a password (press ALT+type 255+release ALT). (- mhddsoftware forum).
We don’t know the password (forgotten/lost/etc):
SAMSUNG
MHDD: You can try entering 32 “B” characters (in capital letters and in Latin) when prompted for a password.
VTOOL: In disk editor mode, find the sector with the text "SECURE" in the negative sectors and clear it (except for the word Secure) and another sector - a copy of the 1st.
SEAGATE
Master password- "Seagate + 25 spaces."
The presence of a terminal (you need to make a cable) will greatly simplify the solution to the problem.
In the terminal:
CTRL-Z
T>GFFF3 (for Barracuda V)
T>/1
1>B200,200
There you will see your password. Then ATA using the F2 and F6 commands with a buffer containing what you saw....
Also for U5,Barracuda II,III,IV you only need to read B0,0.
For 7200.7 you need to enter GFFF2.
W.D.
Master password- "WDCWDCWDCWDCWDCWDCWDCWDCWDCWDCWD".
xB series:
"The password is at the end of the second sector on track -2 in clear text."
Hddl: 57 44 43 00 00 A0 8A - send, 00 01 01 00 0F E0 21 - send, clipboard - receive, view - at the end. 00 01 01 10 0F E0 21 - the same thing, but for the first head.
for WD307AA 272AA, 450AA and 205AA:
"The password is at the end of the third sector on track -1 in clear text."
Hddl: 00 00 00 00 E0 A0 8A - send, 00 01 02 00 0F E0 21 - send, clipboard - receive, view - at the end. 00 01 02 10 0F E0 21 - the same thing, but for the first head.
Fujitsu
fakel.exe: count the modules and look at No. 12 and No. 13.
PC3K: You can rewrite module 0D.
MAXTOR
Master passwords- "Maxtor INIT SECURITY TEST STEP" (for N40P), "Maxtor+26 spaces" (541D).
IBM
Can be used HDDL:. Read the documentation for this program.
PS. There are other effective programs (for example PC3000). If you were unable to remove your password using the above methods, then your path lies with the owner of these products. I also advise you to use search engines on this topic because... There is a lot of information on the net.
